# Script for running the Dockerfile for Traffic Router.
# The Dockerfile sets up a Docker image which can be used for any new container;
# This script simulates the systemd unit file that is used to start traffic router on 
# servers in the real world, but in Docker containers systemd is disabled. 
# Therefore it is important to keep this script up to date with any changes that are
# made to traffic_router/build/build_rpm.sh and traffic_router/build/pom.xml
